INTERNAL-COMBUSTION ENGINE.

PHII-"ER, a citizen of the United States of.

America, ,residing at Collinsville, in the.

county of Madison and State of Illinois,

have invented certain new and useful Improvements in Internal Combustion Engines, of which the following is a specification,

The primary object of this invention is in providing. an improved arrangement of parts whereby the cylinders and other working parts are all inclosed in one casing, thus makin a compact and powerful motor, and by an improved arrangement of power transmitting from the pistons and the crank shaft, the knocking of the moving parts is eliminated.

A further object is in providing means whereby the power derived from a number of cylinders of an internal combustion motor is transmitted to the crank shaft by a single connecting rod. 7

A further object is in providing improved means whereby the throw of the piston conne'eting rods is practically d :e away with; thus avoiding the side lash of the pistons on the cylinders.

A still further object is in providing improved means of lubrication to the pistons,

cylinders and other working parts of an internal combustion engine.

Another Ob ect is in providing a uniform cooling temperature to a number of cylindersofan internal combustion engine, by having a single casing cover and containing all of said cylinders, so that the water surrounding said cylinders will be in one body.

' Another object is in providing an improved rotary valve in which a single valve controls the supplying and exhausting of any number of cylinders of an internal com oustionengine; said valve being always in receiving communication with the charging mixture, and in exhausting communications with the exhaust discharge pipe.

Other and further objects will appear in the specificationsand be specifically pointed out in. the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which Figure 1 is a side elevation of this improved engine showing the connecting rod side. Fig. 2 is a plan view of Fig. 1. with the casing cover removed. Fig. 3 is a hori' Specification of Letters Patent Application filed August 21. 1912.

Fig. 11 is a plan viewof an improved packing ring used in connection with the improved rotary valve.

In the drawings the bedplate 1 has mounted thereon the casing 2 which is positioned by the cap screws 3. Located in said casing 2. and mounted on said bedplate 1, are a series of open ended cylinders iwhich are held in position by the cap-screws 5.

Reciprocably mounted in the cylinders 4; are pistons 6, said pistons being mounted on wrist-pins 7, to which are connected connecting rods 8; said connecting rods being connected to walking beams 9, mounted on a horizontal shaft 10 by the pins 11. Formed '18 which is mounted on the end of a driving shaft it), which is mounted in bearings 20. Formed in the side walls of the casing 2 adjacent its lower end, mounted on the driving shaft 19 on the opposite side of the casing 2, to which the crank 18 is mounted is a fly wheel 21. and mounted on the shaft 19 between said fiy wheel 2.1, and easing 2, is a sprocket 22, on which is mounted a driving chain 23, said driving chain connecting -with a sprocket 24; which sprocket is mounted on an end of a horizontal shaft 25.

The end wheels 26 of valve housing 27. serve as bearings for the said horizontal shaft and located in said valve housing and mounted on the shaft 25, is a rotary valve 28 i said valve being hollow and of a,

drum shape, and has a partition or dividing Web 28 extending the length of said rotary valve 28, forming chambers and 30. Formed-in the periphcry of the rotary valve 28 and communieating with the chamber 29 are ports 31 and 32, said ports communicating with the chamber 29, and forming intake ports, said port-s communicating with the chamber 30 forming exhaust ports. Formed i one end of the chamber 29 is an end Wall 33, and formed at one end of the chamber 30 is an end wall 34.

By an inspection of Fig. it of the drawings, it will be noted that the rotary valve 38 is located at a distance away from the end walls 26 of the valve housing 2'7 forming end chambers 85 and 36. Located on the periphery of the rotary valve 28 adjacent the ends thereof, are packing-rings 37. Formed in the end Wall 26 adjacent the end chamber '35, and at the bottom thereof is an intake pipe opening and formed in the opposite end wall 26 adjacent the end chamber 36 is an exhaust pipe opening 39, Formed in the valve housing 27 and disposed up-Wardly at an anglerof about 45 from the center of the rotary valve 28, are inclined cylinders 40, said cylinders extending from the periphery of said valve to the bedplate 1. Located in said cylinders 40 and hearing against the peripiery of the rotary valve 28, are valve packing-rings 41, carrying the cylinder bearing rings e2, said valve pack ing-rings 41 having a center opening 43 and pressure bearing surfaces 44. Formed in the bedplate 1, between the firing cylinders 4- and cylinders l are openings which form means of communication between said cylinders, mounted on top of the casing 2, is a cover 4-6, which is held in place by the cap-screws -17, and is removable for the. purpose of inspecting the moving parts coir tained therein.

In the operation of this improved internal combustion engine, assuming that the open ing 38 located in one of the end walls '26 of the valve housing 21" has an intake pipe located therein, said intake pipe being for the charging mixture supply, the chambeufi?) will be continually filled with the charging mixture, and as the rotary valve is rotated the ports 31 communicating with the chamber 29 will be brought in commui'iication with the cylinders 40; and at this pointof the intake port communication, the piston 6 which will they be at tile loiverrnd ct the cylinder t will be adjacent th s openiiig, and at a point cfinoving r a charge of l11lX "'C chamber 29 three A the cylinder 40,

through opening 1 piston G has rum stroke, the port or ivin 22a i spirally arranged the cylinders to be charged.

he t ff lroin the into 3 the piston 5 moves on dovv'n-vvardly compression in the cylinder d ieoli tained, and after the compression talten place the point of tiring is reached which will propel the piston back to the upward end of its stroke, at which point the piston begins to descend to'scavenge the cylinder By this time one of the exhaust ports 32 which has communication with the chamber of the rotary valve 28, i in comi'nunication with tl'xe cylinder 4t through the cylinder 40 and opening 45,, so that the descending piston (3 yvill discharge the burnt out into the chamber 30 of the rotary valve 28; and from there they Will be carried on out through the exhaust pipe opening 39, located in the end wall 26 of the valve housing 27, I From an inspection of Fig. t of the drawings and with reference to the valve housing 27 and valve :28it is to he noted that by reason of the chamber 3? termed in the end of the valve housing adjacent the intake opening the chamber formed in the valve 28 will be in continuous communication with the charging mixture, so that as the ports which comnuinieate with said chamber 29, are brought into communicating position with, the cylinders 40, the charging mixture is allowed to enter The chamber 36 formed in the end of the valve housing 27 adjacent the exhaus pipe opening forms means of continuous connnunication of the chamber 30 with the exhaust pipe opening 39.

it is to be noted that the ports 31 and 32 are in communication with the chambers 29 and 30 respectively of the valve 28, which are located about 90" apart in the periphery of said valve and are in alinement with each other, and with the pair of cylinders 40, so that as said valve 28 rotated the intake port 31 will communicate with first one cylinder and then the other, the exhaust port 35) will in turn communicate with said cylinders. As shown there are sets of ports 3i and 32 located on the periphery of the valve 99. one set oi. said ports being din metrically opposed from the other se 1 are formed on the opposite end of the valve 28 on the periphery thereof. This set of intake and exhaust ports is for the purpose of operating on another pair of the cylin ders 4:0 as shown. lnasniuch as there are t cviinders shown pair) the relation of the 31 and 32 is essential in order o take care of the tiring cylii'adez's in i and to accentmodatc the in relation to the chambers A spirally an olivious or} lndrrs all It is readily seen how the connecting rods f4 being mounted to the pistons (S and Walkmg beams being connected to the horizontal shaft 10, will actuate or rock said shaft, then the crank .14 mounted outside of the casing 2 on one end of said shaft 10, will actuate the connecting rod 16 which connecting rod being connm-ted at its lower end to the crank pin 17 of the crank18, which crank is mounted on the end ofthe driving shaft 15) will operate said driving shaft. \Vith this improved manner of operation the connecting rods 8, being connected to the walking beams S), the throw of the stroke of said walking beams is slight, which will practicallyelin'iinato the lateral movement to the connecting rods 8. Therefore the side lash to the pistons of said connecting rods will be eliminated, and the wear on'the pistons and cylinders will be true.

Inasmuch as the rock shaft 10 is actuated by the connecting rods and walking beams, it will then only be necessary to have only one connecting rod to transmit the power from the rock shaft to the driving shaft- 19. This one connecting rod in ci-ninection with the driving shaft, which in transmitting power from a number of cylinders is a de cided iinprovement over the construction of the internal combustion engines, that now have connecting rods from the pistonstothe cranks, as the duty of a connecting rod is heavy, and has to contend with severe knock ing and jarring which loosens the connection of the connecting rods and the cranks; whereas with using only one connecting rod for a number of cylinders as shown the wear will be confined to this one connecting rod, and as said connecting rod is assembled on the outside of the casing 2, itis readily accessible for adjustment and repair. In having a number of cylinders incased by one casing, the water which is used for cooling the. cylinders being contained in said casing and surrounding said cylinders Will he in one body, and the temperature in said body ofwater will be uniform.

In providing an improved cation, lubricating oil is poured into the casing 2', and on the water contained therein,

and after the water becomes heated the oil ill mix with the water and vapor will arise therefrom and the oil laden vapor or steam will penetrate the working parts, and which will provide a perfect lubrication thereto.

To prevent the water in th'e'casin'g 2 from becoming too highly hea'ted,-it'is to be understcod that said water will. be circulated through a radiator, such as is now in common use.

In the construction of this improved internal combustion engine as shown and de;

scribed, a compact and efficient motor can be had, the mbving parts being in easy access ofzinspection by removing the cover a6.

On the periphery of said valve which will prevent escapement of the compression and firing force along the perniheiy of the rotary val e, the packing rings 37 located on the periphery of the valve 28 adacent the ends thereof, are for the purpose of packing said valve against the. escape-- ment of the charging mixture from the chamber 35, and also from the escapement of the burnt gases from the chamber 36; Also by reason of these packing rings 37 bearing against the inside walls of the housing 27 of the valve 28, will answer as pack- The outside diamete of the rotary valve .28 can be made of smaller diameter than the inside diameter of the valve hot r 1;; a nil the rotary valve 2:1 being mounted on in 'llltlfi. 25, will allow for the valve to be of easy running, as the on point. of fri. ioi'ial contact of said valve against the valve housing will be the packing rings 37;, and by reason of said valve being of smaller diameter than the inside diameter of the housing, said valve will not have a'tendency to bind by reason of the expansion caused by the exhausting of theburnt gases through said valve.
